That 1000 A holds steady through the typical panel ambient — only at 60 °C does it step down to 955 A, and at 70 °C to 815 A. The interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V, so it handles high-fault scenarios across common distribution voltages without cascading upstream. This is a line-protection breaker, not a motor-circuit protector; the ETU350 electronic trip unit gives you adjustable long-time (tr 0.5–17 s), short-time (tsd 0.04–0.4 s), and instantaneous (li fixed at 10 kA) response curves. The 3VA2510-5HN32-0HA0 measures 210 mm wide, 320 mm high, and 120 mm deep. ## Coordination and selectivity The ETU350 trip unit's adjustable short-time delay (tsd 0.04–0.4 s) and the fixed instantaneous pickup at 10 kA give you selectivity headroom against downstream breakers. For a 1000 A main feeding 200–400 A feeders, the long-time band (tr 0.5–17 s) lets you coordinate with downstream thermal-magnetic or electronic trip units.","metaTitle":"Siemens 3VA2510-5HN32-0HA0 SENTRON MCCB, 1000 A, 187 kA at 2","metaDescription":"Siemens SENTRON 3VA2510-5HN32-0HA0 molded case circuit breaker, 1000 A continuous, 187 kA at 240 V.
